This lesson incorporates sea surface data collected by NASA satellites. Data for three surface characteristics- height, temperature and speed- are used for several activities. Students examine the differences in speed of currents relative to...(View More) distance from the Equator. Sea surface data anomalies are charted and further analyzed. In addition, surface current data is presented to examine patterns related to El Niño. Note that this is lesson three of five on the Ocean Motion website. Each lesson investigates ocean surface circulation using satellite and model data and can be done independently.

Worldwide patterns and sources of aerosols are analyzed and evaluated for potential hazards to aircraft safety. Using aerosol index maps created from data gathered by the TOMS instrument, student groups will analyze and compare aerosol data from...(View More) either eight consecutive or eight random days. Each group will graph the data, rank the hazard level of their study area and analyze the patterns and probable causes of those aerosols. Directions and materials are included for classes with computer access and for those without computer access. The URL opens to the investigation directory, with links to teacher and student materials, lesson extensions, resources, teaching tips, and assessment strategies. Note that this is the last of three investigations found in the Grades 5-8 Module 1 of Mission Geography. The Mission Geography curriculum integrates data and images from NASA missions with the National Geography Standards. Each of the three investigations in Module 1, while related, can be done independently.(View Less)
